Answer:

Step-by-step explanation:

37) Take two point from the line.

(2 , 0) & (0,4)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{4-0}{0-2}\\\\=\frac{4}{-2}\\\\=-2$

Slope = (-2)

38) (7 , 0) & (3 , 2)

$Slope = \frac{2-0}{3-7}\\\\=\frac{2}{-4}\\\\=\frac{-1}{2}$

39) The line is parallel to x-axis and so its slope is 0

Slope = 0

40) The line is parallel to y-axis and so its slope is undefined

Slope = undefined
